Detailed answer

Hand cream is primarily formulated to moisturize and protect the skin on the hands. While it may help in improving the overall appearance and texture of the skin, it may not specifically target hyperpigmentation on the elbows. For effective treatment of hyperpigmentation, it is recommended to use products that contain ingredients like hydroquinone, alpha hydroxy acids (AHAs), or retinoids, which can help to reduce the production of melanin in the affected areas. Additionally, exfoliating the skin regularly and protecting it from sun damage with SPF can also aid in reducing hyperpigmentation. It is advised to consult a dermatologist for a proper evaluation and personalized treatment plan.
